In the drawings, the main frame of the machine iilustrated, comprises a vrectangular base I and a super structure comprising a front plate 2, a rear plate 3, and an upper tubular support 4 extending between the front plate 2 and rear plate 3, and an intermediate tubular support 5, also extending between the front plate 2 and rear plate 3. Extending through the front and rear plates 2 and 3, respectively, and the tubular support 4, is a tubular turret shaft 6, which is journalled in and projects through bearings I and 8 mounted respectively on the plates 2 and 3. Mounted fast on the projected front end of the turret shaft 5 is turret-type conveyor, indicated as an entirety by 9. In the embodiment of the invention herein illustrated, the turret conveyor 9 is in the nature of a wheel comprising a hub I0, four spokes or arms II spaced apart, and a rim I2, which latter serves as a brake drum.

By reference particularly to Figs. 3 and 5, it will be seen that the radial spokes or arms II of the turret wheel, together with the rim I2, define four circumferentially-spaced openings I3 in the turret wheel. Also by reference, particularly to these Figs. 3 and 5, it will be seen thatl the conveyor wheel 5 carries four like groups I4 of partition holders, and which groups are spaced 90 apart. Each of these groups I4 of partition holders comprises three sets of holders,y respectively indicated by I5, I5 and I1, and each of which sets of holders is adapted to receive and support a different individual partition of a laterally-spaced group of three thereof.

As illustratedherein, the set of holders I5 comprises five individual spring clip holders I5', the set of holders I6 comprises ve individual clip holders I6', and the set of holders I'I' comprises ve individual spring clip holders I'I.

The several individual holders I5', I6 and each comprise four elongated spring iingers I8 that are mounted at their front ends on an adjustably slidable head I9, and have diverging free rear end portions providing receiving mouths for partitions fed horizontally thereto while disposed either horizontally or vertically. In the arrangement illustrated, the head I9 of each holder I5', I6 and Il of each of the holder sets I5, I6 and I? of each group I4 is slidably mounted on a different one of a laterally-spaced group of mounting bars 20, there being a group of vmounting bars 2! for each group I4 of holders, and each of which groups of bars 20 extends across a different turret wheel opening I3. The several heads I9 are adapted to be locked in adjusted positions by means of set screws 2l, and by adjusting the heads I9 on the mounting bars 20, it is easy to vary the lateral spacing between the holder groups I5, IB and I1, and to obtain alignment between each of the holders of each group.

The mounting bars 2E) are each provided at one end with a slide head 22, and its other end with a set screw-equipped slide head 23. The slide heads 22 and 23 are respectively mounted on laterally-spaced parallel rails '24, and are adapted to be locked in adjusted positions thereon by the set screws 25, acting through wedge blocks 25. By varying the spacing between the mounting bars 20, the groups of holders I5, I6 and I'I may be adjusted to accommodate partitions of different lengths and slot spacings. The rails 24 are rigidly mounted on the turret at opposite ends andportions, as best showny at 21 in Figs. 3, 6 and 8.

The spring clip holders I5, I6 and I1 are adapted to receive to different depths partitions fed edgewise thereto, in this case, the depth to which partitions are fed into the holders being dependent upon the depths of the partitions themselves. For limiting the depthto which partitions may be fed into the friction type spring clip holders I5', I6 and I'I, and for use in ejecting such partitions from the holders, we provide, as an important feature of the instant invention, combinedf'backfstops and electing devices 28 of which, in accordance with the present y illustration, there are a group of four for each group I4 of partition holders. These devices 28 Vmounted fast in the turretVv wheel.

'|j6l and i|.'| for the-purposes of limiting thefmovements of the partitionsv into the holdersl andfor ejecting the same from theholders. The several backstop 'and rejecting devices 2*8 oiV ffeach groupv thereof `have Ytheir 'forwardly extended dium-offset screW-equippedsliding blocks 30, a

ing` therebetween. By reference, particularly to Figs, 5 and 6,V it will be vseen that the set screws 133i of slide blocks 30 work through a common slot 34 in'the guideheads 3|. Forward sliding movements of the slotted heads -3 on the guide rods 32 areadjustably but positively limi-ted by set screw stop collars f35'on1said rods 32,v the `col-lars 35 being. adjusted-to positions determined 'bythe varying depths of=-partitions being operated on by the `machine.` In the arrangement illustrated-'the slotted guide heads 3| lare yield- 1inglyfbiased in a forward direction-toward said `stop-.collars 35v by coil compression springs 3 5 mountec'lvon the guide rods 32,-see particularly tFigs. 5` and 6. It will now be seen, particularly Aby reference to Figs. 5 and 6, that the devices '28. when in their nor-malv positions shown, serve as stop devicesffor positively but adjustably-varifably'limiting the depth partitions `may be inserted into the-spring` clip holders I5', r'I5' and v|'|'.and it will further be seenfby reference to fsaid figures that these devices 'V28 may-be moved :rearwardly againstithe biasing action of springs i "36 to veject partitions from the holders.

The turrent conveyor 9 is intermediately driven in a clockwise 'direction with respect to Figs. 3 and5 to `bring the same-successively into flfour different index positions spaced 90 apart. VIneach of these four index positions ofv the lturfret, a different turret carried group ofV partition holders I4V will be located in an assembly zone or station A` (see particularly Figs. 3y and 5);;

The shaft 42 drives alow speed power-shaft 431 through conventional` speed reducing mechanism', not shown, 'but contained within a gear box 44. The shaft 43 comprises an intermediate section and;V twoend sections suitably connected-thereto by suitable conventional couplings 4-5, and one-end portion ofthe shaft `43 is` suitably-journalled in the gear -box 44 and the other end portionoff the shaft- 431s journalled' in agear'box 455, seeparticu-larly-Fig. :24, `The lowspeedshaft-43 drivesa short crank shaft 41 through conventional transmission mechanism-not shown but contained within gear box 46, see particularly Figs. 2 and '24. The

crank shaft 45|Y is driven in a clockwise-direction with respect-to Fig. 24- and by reference to said figureandFig. 2,- it-wi1l be seen that this crank shaft 4'|V is journalledfat one end ina ybearing-48 carriedv by the gearbox-45'- and at its intermediate portion by a bearing 49 carried-'by-theback plate 3 of the base ofthe machine.'Y Mounted fast on the proj ected-rea-r endf ofthe crank; shaft 41 isa crank' 50 (see-'particularly Figs. 2 and-'8) which operates an upwardly extendedv gearrack 5|, shown bestin Figs. -8 145 and 16: This gear rack 5| meshesgwith agear--segment '521thatis journalledonvthe projected rearfend of the turret shaft E throughthe medium of the hub *53 of a circular indexing flange-54. By reference particularly toFig. 1'7, vit willl be seen thatthe gear segment-52 is axially journa-iled on the 'hub 53 off indexing angel'and that the saidhub- 53 is keyed fast on the turretv shaft S, atl 55. The turret shaft 6` is tubular andl is journalled in the bearings V'I and `8A andv extendsthrough the tubular support 4, Vsee particularly Figs. -2V and r1. As previouslyV indicated, the hub it orme turret wheel A9 mounted f fast4 on-y theV projected With the turret segment 52- which oats upon turret shaft' e is Voscillatedthroughfanarc of 90 for each rotation of crank-shaftV 4-1, see particularly Figs.

particularly-Figs. 15 and l'and 17. Theturret driving clutch mechanismA (Figs. 1,5 to 11'? inelusive) comprise a spring pressedclutchdog5`| which is engageable in any one-of four circum- -ferentially spaced indexing notches '51 inthe indexing flange 54`and which notches are angularly spaced90vapart The boltrlilreclutchidog 5'!` is radiallyslidably mounted in a guideway defined by a clutch mountingi) fast on thewgear segment 5,2, see particularly Figs. 15, 16, v.1* 7' Vand 2K0, `and is inwardly springlpressed toward the index-ing dia-nge 54a by a coil" compression spring 66. The clutch dog 51 is normally engaged in one of the indexing notches 58 and is so engaged kduring the entire downward movement of the gear rack At the time, or just slightly prior to the time, the gear rack 5| reaches its lowermost position at the end of the downward turret operating stroke of said rack and its driven segment 52, the clutch dog 51 is retracted from its 4engaged indexing notch 58 by oscillatory clutch releasing arm 6| having an-adjustable pusher head 62 which engages the radially inner edge of a flange 63 on the bolt-like clutch dog 51. The oscillatory clutch releasing arm 6| is inter- `mediately pivoted at 64 and at its lower end is provided with a head 65 which is subject to the action of a roller 66 carried by the free end of a rotary arm 61 mounted fast on shaft 41, see particularly Figs. 2 and 8. With the arrangement just described, the clutch dog 51 will be retracted from an engaged indexing notch 58 once for each rotation of shaft 41 and once for each 90 of Amovement of turret shaft 6. Of course, the roller 66 engages the head 65 of the oscillatory clutch releasing arm 6| for only a few degrees of rotation on arm 61 and for only suicient angular movement of gear segment 52 to permit movement of the latch dog 51 out of registration with the previously engaged notch 58.

By reference particularly to Figs. 8, 15, 16 and 18, it will be seen that the oscillatory clutch releasing arm 6| is actually operated in a clutch releasing direction by the roller-equipped rotary arm 61, but is automatically returned to its Aclutch engaged position by a coil compression spring 68 operating through a hollow plunger 69 slidably mounted in a bracket flange 10 fast on the frame of the machine as illustrated. The spring 68 is mounted on a plunger rod 1| fast on the closed end of the hollow plunger 69, see Fig. 18. Extreme movements of the oscillatory clutch releasing arm 6| in a clutch releasing direction are dampened by an adjustable rubber buffer 12, shown best in Fig. 18.

The gear rack 5| is maintained in mesh with the gear segment 52 by a pair of guide rollers 13 journalled on the free end portions of a rocker frame 14 that is pivoted on the hub 15 of gear segment 52 (see particularly Fig. 17). v

Positive indexing of the turret in each of its four indexed positions or stations is accomplished by a spring pressed indexing plunger 16 (see Figs. l5, 16 and 19) that is slidably mounted in a bearing 11 mounted fast on a bracket 18 projecting from the rear plate of the main frame of the machine. pressed indexing plunger 16 is sized to fit snugly in any one of the four indexing notches 58, and is spring pressed toward the indexing flange 54 by a compression spring 19, shown best in Figs. 15 and 16. The spring pressed indexing plunger or bolt 16 rides on the circular face of the indexing flange 54 during the major part of each 90 movement thereof, and is spring pressed into a cooperating indexing notch 58 each time such a notch comes into registration therewith. Retraction of the indexing bolt or plunger 16 from the cooperating indexing notches 58 at the initiation of each 90 of rotation of the indexing ila-nge is accomplished by a cam 80 fast on and projecting radially from gear segment 52, and a cooperating latch retracting roller 8| journalled on indexing plunger 16 through the medium of a spindle 82 anchored in the plunger 16 and working in a suitable slot in the bearing 11. With this arrangement, the indexing plunger 16 The free end of the spring is mechanically and positively retracted from an engaged indexing notch 58 just prior to the initiation of each movement of indexing flange 54, and is maintained mechanically retracted until out of registration with the last engaged notch 58. Reverse or counterclockwise movements of the indexing flange 54 are positively prevented by a spring pressed pawl 83 shown best in Figs. 15, 16 and 17. Of course, this also prevents any reverse movement of the turret shaft 6 and parts carried thereby.

Because the turret is crank-operated, and because each 90 movement of the turret commences with the crank at dead center and ends with the crank at dead center, the speed of the turret will be gradually accelerated during the first half of each 90 movement and will be correspondingly gradually reduced during the latter half of each 90 movement, so that the speed of the turret will have been reduced close to zero at the time it reaches each of the four indexing positions. Hence, theoretically, at least, movement of the turret will have been reduced to, or close to, zero each time the indexing plunger comes into registration with an indexing notch 58. However, in practice, such an ideal condition is not usually obtainable without the use of auxiliary braking mechanism, since there is inevitably a certain amount of slack or back-lash and torsional shaft Whip in the turret driving mechanism, which tends to permit the turret to slightly overrun during the speed-retarding half of each turret-operating cycle. For this reason, we preferably employ automatic turret braking mechanism which comes into play during the latter or speed-reducing half of each 90 operating movement of the turret, to prevent the inertia of the turret from taking up the slack in its driving mechanism, and which insures substantially zero motion of the turret at each indexing station. The braking mechanism herein illustrated is a material improvement over that illustrated in the before-identified Porter application, and will immediately be described. The brake proper comprises the brake drum-acting rim I2 of the turret 9 and a spring-actuated brake shoe 84 (see particularly Figs. 3, 4 and 5).

The brake shoe 84 is segmental and is equipped kwith the usual friction facing 85. The shoe 84 is pivotally mounted at its intermediate portion, on the intermediate portion of arm 86 forming part of the brake releasing linkage. One end of the arm 86 is pivoted at 81 to a. frame mounting bracket 88. The brake shoe 84 is yieldingly urged against the brake rim I2 of the turret by a pair of coil compression springs 89 to varying degrees of pressure determined by an adjustment bolt 98 and follower 9|. The brake releasing linkage comprises the intermediately pivoted link 86, a laterally-spaced pair of rigid links 92, a crank 93 fast on an oscillatory shaft 94 that extends through the front and rear plates of the ating rst half of each 90 movement of the turret, being then released by cam 91 and re-set by springs 89 during the speed-reducing latter half of each 90 movement of the turret. Actually,

the brake remains spring-set during idleperiods of. theeturret,, and. is cam-released just, prior, to the initiation .of reach 9,0? cycle of the fturret.

Theecombined-back-stops-andp-artitionzejectors fon eachf group I4" of partition holders are auto'- matically advanced 'rearwardly from` their normal forwardly-located stop ,positions to their rearwardly. extendedpartition ejectoi'positions; and returned back to their normal, stop positions, once-zu for each complete 360l movement of the turret, or once for, each four 90 cycles of` movementi-ofv the turret, thsoccurring each time-a group of fdevices28fanda cooperatingagroup I t of partitionl holders are atL rest in the. ejector" zone C.
